It's not vastly underrated in terms of people liking it but I think it's a little underlooked at as having a lot more substance underneath. Symbolically. I'm sure a lot of aliens used disguises. But how many of the disguises themselves were intentionally manipulative? As a means of engaging a pre-existing trust to lure in victims? Making them hunters, in some cases sport. And how many had a face that was like a product itself? The movie's incorporation of fast food restaurants from Frame #1 (post title sequence) is a silent recognition of Ronald McDonald as Clown Mascot for an industry which brightly colors and attractively packages their dangerous product that slowly kills you (the same as cigarettes, alcohol, and harmful chemicals; ala- Tim Burton's Batman). Throughout, we have scene after scene of the clowns killing people but we always see their faces close up with dead expressions as they gather in groups forming an army which again goes totally unspoken of in the film's dialogue. The movie kind of found a way to creatively depict a genocide and Home Invasion in the most horrific sense it could ever happen: we actually watch a platoon of them swoop in and raid houses like a vacuum sucking up ants.

i'm shocked to see anything positive said about Signs. ugh. i remember hating that movie.

I'll defend Signs - to a degree at least. It has some great high-tension set pieces, particularly when the alien is trapped in the pantry. But, yeah, the film still goes hell bound off the rails by the time it's over.

I put my vote in for Body Snatchers. For any version, although I haven't seen the Kidman one. I really just love the concept. No space ships. No laser guns. No army battles. They just take you in your sleep. Brilliant.

Between The Thing or the remake of Invasion of the Body Snatchers this is pretty difficult

but had to give it to Body Snatchers. The invasion is dealt with so perfectly and it shows the effect of the invasion on a metropolitan scale, and not just a group of guys working in the middle of nowhere. And it's much more subtle compared to The Thing
Don't get me wrong though, The Thing is genius.

I do love Signs and Dark Skies too.

I love The Thing and Night of the Creeps, but neither had the big dumb cheese staying power of Predator. When I was a kid and saw that for the first time, it blew my brains. Yes, it is nowhere near the caliber of several of these films, but damn if it isn't endlessly watchable and enjoyable. /Nostalgia
